BORIS Johnson has been urged to cancel his trip to Scotland tomorrow, with MPs saying he should only travel if he intends on doing “real work”.

There’s speculation the Prime Minister could be visiting Perthshire or the central belt.

It’s understood he’ll be meeting troops from one of the Army’s 11 Vaccination Centre Setup Teams as they help build one of 80 new sites.

Nevertheless, Alistair Carmichael, the former secretary of state for Scotland, was wary of the trip. He accused Johnson of treating his role as Minister for the Union “like a punchline”.

The veteran LibDem said: “Ronald Reagan famously said that the scariest words in the English language were ‘I am from the government and I am here to help you’.

“For those of us making the case against separation, the Prime Minister making a day trip of this sort has a similar ring.”

Currently, it’s against the law to travel from England into Scotland without a “reasonable excuse”.

The Prime Minister – and everyone else – can “travel for work” but only when that cannot be done from home.

Carmichael said the guidance was clear.

“If the Prime Minister is intending to travel then he had better have a real reason and some real work to do – not just staged photoshoots,” he said.

“When the Prime Minister came to Scotland last summer, he posed for the cameras with Orkney crab and promised good times ahead.

“If he’s determined to visit again, he should meet with those same producers to apologise for breaking his promises and wrecking their access to vital European markets.

“Bungling Boris Johnson has been consistently the most effective recruiting sergeant the nationalists could dream of.

“If he wants to change that perception then he could start by treating his title as Minister for the Union a little less like a punchline.”

The National:

Pete Wishart, the SNP MP for Perth and North Perthshire claimed the trip defied all public health measures.

He told the Courier: “At this critical time, when it looks as if we might finally be seeing the numbers of infection falling again, it is hugely troublesome to hear that Boris Johnson plans to defy all the stay at home messaging and travel from London to Scotland.

“Some London boroughs still see infection rates of over 700 per 100,000 of population, at a time when the average rate across Perth and Kinross is below 150 per 100,000.

“I would politely, but firmly suggest to the Prime Minister that this trip is not essential, it is not appropriate and I think that most people in Scotland would agree with that point.”

But Alister Jack, the Secretary of State for Scotland insisted Johnson did have a “good reason to visit”.

“He is Prime Minister of the UK. All the people on the trip with him will be lateral-flow tested before they leave and all Covid rules will be adhered to,” Jack said.

“We know there is a geographical border but it is not a physical border. We are one United Kingdom and he is Prime Minister of that United Kingdom,” Jack told The Herald.

According to The Guardian, during his trip, Johnson is set to announce “that he considers the UK’s existing constitutional architecture is not working”.

He will reportedly unveil a “third way” approach, somewhere between the status quo and independence.

This will be “based on the principle of the UK adding value to the devolved settlement, as well as launching an all-UK strategy that could involve new and wider devolution and a more federal structure to the UK’s constitutional arrangements, potentially extending to reform of the House of Lords”.

Over the weekend, it was revealed that Michael Gove had met with Gordon Brown, to talk about building the case for the Union.

Meanwhile, yesterday Alun Evans, director of the Scotland Office between 2012-15, criticised Johnson for putting his head in the sand over a second vote.

In a letter to the Times, he suggested there should be a third option of “home rule” on any ballot and a requirement that Yes would win a 60% “super-majority”.
